ALOS\_pre\_process\_SS

## NAME

ALOS\_pre\_process\_SS - ALOS\_pre\_process\_SS

## SYNOPSIS

**ALOS\_pre\_process\_SS** *imagefile LEDfile* \[*-near near\_range*\] \[*-radius RE*\] \[*-swath swath#*\] \[*-burst\_skip*\] \[*-num\_burst*\] \[*-swap*\] \[*-V*\] \[*-debug*\] \[*-quiet*\]

## DESCRIPTION

This program is part of GMTSAR.

creates data.raw and writes out parameters (PRM format) to stdout

imagefile       ALOS Level 1.0 complex file (CEOS format): LEDfile         ALOS Level 1.0 LED file (CEOS leaderfile format):

-

  options:

**-near** near\_range       specify the near\_range (m) **-radius** RE             specify the local earth radius (m) **-swath**                 specify swath number 1-5 \[default 4\] **-burst\_skip**            number of burst to skip before starting output (1559 lines/burst) **-num\_burst**             number of burst to process \[default all\]

-

  there are 72 bursts in a WB1 frame

**-swap**                  do byte-swap (should be automatic) **-fd1** \[DOPP\]            sets doppler centroid \[fd1\] to DOPP **-V**                     verbose write information) **-debug**                 write even more information **-quiet**                 don't write any information Example: ALOS\_pre\_process\_SS IMG-HH-ALPSRS049842950-W1.0\_\_D LED-ALPSRS049842950-W1.0\_\_D **-near** 847916 **-radius** 6371668.872945 **-burst\_skip** 5 **-num\_burst** 36
